Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated galvanized layer on its surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes have a wide range of applications. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in marine oil fields. They are also used as pipes for oil heaters, condensers, and coal tar wash oil exchangers in chemical coking equipment, as well as pipes for support structures in wharf piles and mining tunnels.
